Service call for a system not keeping up and noisy. Technician arrived to find a faulty low press Cut out switch dropping out and causing the compressor to sound terrible. Also the metering device is restricted causing a low suction pressure and a freezing coil. The condenser is also very dirty throwing off refrigerant pressures. The customer wants to replace the condenser and evaporator coil to have a peace of mind that the system will continue to work and have a new warranty.
